The unit is fine, it is located in 5 minutes walk from MBK and Siam Discovery, it is very convenient for shopping. Also there is a desk which is a huge plus. It's very quiet at nights and pretty safe. We also got a free coffee/tea/water as a bonus.
Hataipat's parents are very hospitable people, they took us from airport right to the condo apartment, they told us a lot about places we should visit in Bangkok and even offered a visit to China Town or noodle cafe.
As for downsides, unit had a ton of ants everywhere - kitchen, toilet, bedroom, which were very annoying + floors were dirty when we checked in(but there is everything you need to make a cleaning available, so it's kind of fine).
Thanks for the apartment Hataipat, we will consider this listing in future Bangkok trips.
Best wishes!
